Tobias Müller 659c4fad56 Change version to git describe and make set-able from outside 
Change version to use git describe instead of git log as this will also work
if tags are present and make the version string set-able from outside as a
parameter to cmake, so that package managers can set this if building outside
of a git working tree.

David Shah 7142db28a8 HeAP: Make HeAP placer optional 
A CMake option 'BUILD_HEAP' (default on) configures building of the
HeAP placer and the associated Eigen3 dependency.

Default for the iCE40 is SA placer, with --heap-placer to use HeAP

Default for the ECP5 is HeAP placer, as SA placer can take 1hr+ for
large ECP5 designs and HeAP tends to give better QoR. --sa-placer can
be used to use SA instead, and auto-fallback to SA if HeAP not built.
